Agentic video editor

The agentic video editor for product demos

Definition

What is an agentic video editor?

A video editor run by an AI agent instead of by you. You give it a goal and your material, and it plans the video, uses editing tools to make it, checks the result and revises it from your feedback. A timeline editor waits for every cut. A prompt-to-video generator renders new footage. An agentic editor works on your own footage and gets it to finished.

Reads
Opens your site and captures its real pages, copy and brand. Watches your screen recording if you add one, and reads your GitHub repo if you link it.
Plans
Writes a storyboard and the voice-over, and puts every guess in Director's notes so you can correct it before a frame is made.
Edits
Cuts your footage to the voice, lays out each shot, and adds music and sound. Then it makes a file for every feed you post to.
Checks
Watches its own cut before you see it, and fixes what fails the continuity check.
Revises
Takes changes in a sentence, or at an exact moment in the video, and gives you a new version. Every earlier version stays.
Remembers
Say “always” or “never” and it saves a rule to the project's memory, so the next video follows it without being told.

What it checks before you see a frame

  • Product too small to see
  • Blank or frozen frames
  • Loudness and clipping
  • Silences and overlapping voice
  • Running over length

Each of these started from a URL. The Director captured the product's own pages, wrote the voice-over and cut them into a launch video. No stock footage, no generated screens.

For your agent

Run it from Claude, ChatGPT or Cursor

Demo Editor has an MCP server, so the agent you already work with can hand the Director a video. In Claude or ChatGPT, add a custom connector with this URL and sign in. In Claude Code or Cursor, use a token from Settings → API & MCP.

Frequently asked

Questions about agentic video editing

What is an agentic video editor?

A video editor run by an AI agent instead of by you. You give it a goal and your material, and it plans the video, uses editing tools to make it, checks the result and revises it from your feedback. A timeline editor waits for every cut. A prompt-to-video generator renders new footage. An agentic editor works on your own footage and gets it to finished.

How is an agentic video editor different from an AI video generator?

A generator renders new pixels from a prompt, so it shows what a model imagines. An agentic editor works with what you already have. Demo Editor's Director cuts your real site and screen recordings, so the video shows your actual product. It never invents features or results your product doesn't have.

What does the Director do on its own?

It reads your site and any recording, screenshots or repo you add, writes the storyboard and voice-over, cuts the footage to the voice, adds music and sound, and checks its own cut before you see it: text cut off or overlapping, text outside each platform's safe zone, contrast too low to read, product too small to see, blank or frozen frames, loudness and clipping, silences and overlapping voice, running over length. A video takes about 20 minutes.

Do I stay in control of the edit?

Yes. You read the storyboard and the Director's notes before any frame is made. After that you change the video by asking, in a sentence or at an exact moment, and each change is a new version you can compare with the last. Rules you give it once are saved to the project's memory.

Can my own AI agent use Demo Editor?

Yes. Demo Editor has an MCP server at https://mcp.demoeditor.com/mcp. Add it to Claude, ChatGPT, Claude Code or Cursor, and your agent can start a video from a URL, follow its progress, leave the Director a note, and make a version B or a version in another language.

Do I need to know video editing?

No. There's no timeline to learn. Paste your URL, read the storyboard, and tell the Director what to change, the way you'd brief a person.

Paste your URL. The Director takes it from there.
